In a nutshell

Donald Trump - there's no one inside to look at.  There isn't an inner life that is being obscured by self-blindness.  There aren't values and sympathies and connections to other people that constitute the self   - an inner life. He's empty.  He doesn't know himself because there's no one to know.  There's a whole bunch of impulses and apetites - most of them aggressive and destructive, but there's no self.
